Monoclonius!

Your welcome. And same here, I haven't really talk about it in ages.

I like them even more retroactively, knowing how insanely accurate they were. Bob Bakker was involved in the design process, no lie.

Well, Monoclonius reminds me of dinoriders mostly because the dino-riders monoclonius was so memorable. Also, my first childhood dinosaur books usually featured monoclonius, I assume this was at the time that centrosaurus was considered a junior synonym.

I was fascinated later by it, as I grew up, because if it was a valid taxon, it is extremely un-adorned. Was it perhaps a neotenic ceratopsian? We now have tatankaceratops, which could be considered to trike what monoclonius is to centrosaurus, maybe isolated dwarfed populations of ceratopsians could have ended up like this. I think some study of centrosaurus bonebed material should be undertaken to find out if the juveniles of the same size look anything like mono. I am still hoping against hope that mono is a valid taxon, just a plain lookin guy with that adorable hooked nose horn.
